Deep draw ratio limitation of PLA vacuum forming

문제 현상

The vacuum deep draw ratio of PLA sheet is limited and cannot reach the level of PP.

원인 분석

The ductility of PLA is limited, and the deep draw ratio is <2:1, otherwise it breaks.

해결 방법

Select high-ductility PLA grades; raise the sheet temperature; use an auxiliary plug.

핵심 요약

The deep draw ratio of PLA is a design constraint.
